2014 BMW 320I

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.

In a letter dated September 26, 2013, BMW Group submitted a safety recall notice to NHTSA identifying a defect condition in the vacuum pump oil supply that may result in loss of power assist braking in 76,191 model year (MY) 2012 through 2014 BMW 3-Series, 5-Series, X1 SAV, X3 SAV, and Z4 vehicles equipped with 4-cylinder engines (NHTSA Recall 13V-454).According to BMW, movement of the seal disk within the camshaft may result in blocking of the oil supply to the vacuum pump, resulting in improper pump operation and loss of power assist braking.On July 11, 2013, BMW initiated a change to the camshaft geometry that prevented the seal disk from blocking the oil port.BMW has not received any braking complaints related to loss of power assist after the design change was implemented in production.The owners of all affected vehicles will be contacted by mail and asked to take their vehicle to a BMW dealer who will install a locking ring into the camshaft to keep the seal disk in its proper location.BMW expects to begin dealer and owner notification in November 2013 and complete dealer and owner notification in December when the remedy is expected to be available.Based on the actions taken by BMW, this investigation is closed.

I was driving on a on a busy interstate after work and out of nowhere I get the Temperature warning and start losing power. This is Dangerous! I am submitting this complaint to report a safety‑related defect involving the electric water pump on my 2014 BMW 320i. This issue is widely documented among BMW owners, and several 3‑Series models from the same production years have been included in recalls or service bulletins for premature water pump failure. However, the 2014 BMW 320i (F30 chassis, N20/N26 engine) is not included, despite experiencing the same failure pattern. In my case, the water pump failed without warning. During the coolant bleeding process, there was no circulation or pump activation, indicating a complete pump malfunction. This is consistent with the known failure mode of BMW’s electric water pumps, which can stop working suddenly and cause rapid engine overheating. Because the pump is electronically controlled, there is often no gradual symptom—only an abrupt loss of coolant flow that can lead to engine damage within minutes. This defect poses a significant safety risk. A sudden water pump failure can cause the vehicle to overheat while driving, potentially resulting in engine shutdown, loss of power, or being stranded in unsafe conditions. I was driving on a 2 hour drive on the country road and all of the sudden I received an engine overheating warning and began experiencing a loss of power. Given that BMW has acknowledged similar failures in other 3‑Series models of the same year, it is unclear why the 320i is excluded, despite sharing the same engine family and pump design. I respectfully request that NHTSA review this issue and consider expanding the scope of existing investigations or recalls to include the 2014 BMW 320i. Owners should not be responsible for costly repairs related to a known, widespread defect that affects vehicle safety and reliability.

The contact owns a 2014 BMW 320I. The contact stated that after pulling into a parking lot at approximately 10 MPH and shifting the vehicle into park(P), the message that the engine was overheating was displayed on the instrument panel. After waiting a while for the engine to cool down the contact restarted the vehicle and exited the parking lot. The contact stated that the vehicle began hesitating and sputtering as if the vehicle was going to stall. The contact pulled into another nearby parking lot to park and turn off the vehicle. The vehicle was towed to a certified mechanic and the contact was informed that the water pump had failed and needed to be replaced. The vehicle had not been officially diagnosed. The vehicle had not been repaired. The mechanic referred the contact to the manufacturer. The manufacturer was made aware of the failure. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was 95,000.

I own a 2014 BMW 320IX and first time today, August 20th the Engine Overheat message came on my dashboard and then started to go idle and appear that it was about to die. Upon letting the car sit for a few hours to cool off, within a quarter of a mile of driving the car again the light came up and started to idle and felt like it was going to die again. Twice today, I was left stranded in parking lot and to call a tow truck to have it towed to an independent auto mechanic that fixes BMW. This evening I noticed a recall for 2012 - 2014 BMW 328 and 328IX. This is also an issue with the 2014 BMW 320IX models too. I need this recall to also include the 320IX model. How can this be updated and approved as soon as possible to include this car model and year? Prior to today, there was no indication of an engine or have I ever seen the over heat message come on today. I need to know if I need to take it to a BMW dealership or can it be fixed through the independent car mechanic?

Timing chain issue that is common with the BMW n20 engines. The chain is starting to loosen and have some slack. Afraid it could brake and jump teeth as it does it so many online horror stories wrecking the car's engine after it breaks and gets sucked into it. I believe a recall should hopefully happen. A sorts of class action lawsuits and settlements but no recall yet.

This is a serious problem with the handling of this car in standing water situations. This car immediately begins to hydroplane when it encounters standing water, every time. We had been lucky so far of the numerous instances we had encountered with this vehicle hydroplaning and rotating. Always slowing down when encountering rain to avoid these situations. Tonight 08-13-2022, we were driving on the highway where the posted speed limit was 70mph. We were encountering on and off heavy rain. Crossing a bridge at approximately 15 mph under the speed limit in moderate rain when the car completely lost it's grip on the road and went out of control, like on ice and was unrecoverable. We were hit by a vehicle passing us who was not experiencing the same hydroplaning problem. This has been an ongoing problem with this vehicle and I notified my service advisor at BMW about the problem, but he said it was common and he had even been in an accident with his BMW due to hydroplaning. He said there was nothing they could do about it. The tires were in good condition, recently purchased, and there is not reason this vehicle should not have handled the situation like all of the other vehicles on the road were.(We were the slowest vehicle).

The basic conditions for initializing the power windows are not met.

The electrical system of BMW vehicles has been subject to an ongoing development process over the last few years. This has led to increased demands being placed on the battery. This document covers important information for the dealer on how to handle “discharged battery” complaints.

After programming the head unit (HU-H2), activating the FSC (German word Freischaltcode) Enabling Codes repeatedly fails.

Exterior rear lights do not work.

The 3G network in the US has been shut down. This means that only the 4G network will be available. In the 4G network, voice calls will be transferred via the Voice over LTE (VoLTE) function. For this purpose, the SIM card must perform an IMS registration in the mobile communication network. Due to a production error, the telematics control units were delivered without an IMS configuration. The Connected Drive voice services (Concierge Call, BMW Assistance, and emergency call voice) can no longer be used regionally in the US in vehicle with telematics control units ATM-1 and TCB-4G. Voice control of the vehicle and all other telephone (paired mobile devices) functions are not affected. Emergency call location data is unaffected.

After an automatic engine start (MSA start), the transmission intermittently goes into the Park "P" or Neutral "N" position without any customer influence.
